You can use this function with strip_tags function to print not linked term list:
```
echo strip_tags( get_the_term_list( $post->ID, 'job_titles', '', ', ') )
```
This prints something like this:

Designer, Front-end Developer, Developer
- WordPress coding standards suggest that instead of `strip_tags` we should use the more comprehensive `wp_strip_all_tags` instead.
